timing retard for nitrous .

jimjimjimmy said

i have a msd 6al with the msd billet distributor with no VA and want to run a timing retard , and was looking at the msd 8987 but it says to lock out your timing which i do not want to do. can i run it with my mech advance if not is there another setup i can use ?

This is an example of when it’s ok to lock out a distributor. It’s best to be able to control the curve through the box if you can.

OTOH, if you set up the curve correctly you can leave the curve in it and run the boost retard.

For what you are doing I think a better box would be a good investment...something that can control the timing curve after the mechanical advanced it all in. Something you can change the slope of the curve with.
